Answer:

put the value m=1/2

3m(4m+5)=3

⇒3×1/2(4×1/2+5)+3

⇒3/2(2+5)+3

⇒6/2+15/2+3

⇒37 ans.

Step-by-step explanation:

For the equation, (4m-5)(3m+3)=37 value of m are 2.21 and -1.96

Equation consist of 2 expression equivalent to each other.

Given the following equation:

(4m-5)(3m+3)=37

To calculate the value of m as follows:

4m(3m+3)-5(3m+3)=37

12m²+12m-15m-15=37

12m²-3m-52=0.................................m)

Using discriminant formula:

[tex]d=b^2-4ac.............................1\\x=\dfrac{-b\pm\sqrt d}{2a}............................2[/tex]

Here, from equation m)

a=12, b=-3, c=-52

Substituting in equation 1

d=(-3)²-4(12)(-52)

d=2505

√d=50.04

[tex]m=\dfrac{3\pm 50.04}{2\times 12}\\\\m=2.21 \text{\ and\ } m=-1.96[/tex]

Thus value of m are 2.21 and -1.96

Answer:

Step-by-step explanation:

Using confidence interval concepts, it is found that:

a)

The 99% confidence interval for the proportion of all adult Americans who believe in astrology is (0.244, 0.296).

The interpretation is:

iii. We are 99% confident that this interval contains the true population mean.

b)

A sample size of 664 would be required.

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm M[/tex]

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the z-score that has a p-value of [tex]\frac{1+\alpha}{2}[/tex].

The interpretation of a x% confidence interval between a and b is that we are x% confidence that the true population mean lies in this interval, thus, option iii is correct.

In this problem:

Then:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]M = 2.575\sqrt{\frac{0.27(0.73)}{2005}}[/tex]

[tex]M = 0.026[/tex]

The interval is:

[tex]M - \pi = 0.27 - 0.026 = 0.244[/tex]

[tex]M + \pi = 0.27 + 0.026 = 0.296[/tex]

The 99% confidence interval for the proportion of all adult Americans who believe in astrology is (0.244, 0.296).

Item b:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.05 = 2.575\sqrt{\frac{0.5(0.5)}{n}}[/tex]

[tex]0.05\sqrt{n} = 2.575(0.5)[/tex]

Dividing both sides by 0.05.

[tex]\sqrt{n} = 2.575(10)[/tex]

[tex](\sqrt{n})^2 = [2.575(10)]^2[/tex]

[tex]n = 663.1[/tex]

Rounding up:

A sample size of 664 would be required.

The correct option is C. P cannot be the midpoint.

Midpoint, as the word suggests, means the point which lies in the middle of something. The midpoint of a line segment means a point which lies in the mid of the given line segment.

here, we have,

Since EN≅NG, therefore, the length of the two segments will be equal, which means P can not be the midpoint of the line segment EG.

Hence, the correct option is C. P cannot be the midpoint.

Answer:

D

Step-by-step explanation:

It is because you can see the line pass through the value 0 in x-axis while 6 in y-axis which gives the first coordinate (x,y) = (0,6) and the line also past through the value of 5 in x-axis and 1 in y-axis which gives the second coordinate is (1,5).

So it is true that the line did go through at points (0,6) and (1,5).

Step-by-step explanation:

Multiplying anything by zero equals zero. So if either term equals zero the equation is true.

(x-6)(x+5)=0

So if x=-5 or 6 the above is true.

x=(-5,6)

Answer:

the answers I found are 6 and -5

if you separate the two and equate them to 0 you will get the answers like this :

x - 6 = 0. or x + 5 = 0

x= 6. or x = -5

Answer:

The answer is c

this is the answer because Find the least common denominator or LCM of the two denominators:

LCM of 3 and 8 is 24

Next, find the equivalent fraction of both fractional numbers with denominator 24

For the 1st fraction, since 3 × 8 = 24,

1/3 = 1/3 × 3/8 = 8/24

Likewise, for the 2nd fraction, since 8 × 3 = 24,

3/8 = 3/8 × 1/3= 9/24

Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction

8/24 < 9/24

or 1/3 < 3/8
